試圖從過去24小時收集所有的鳴叫，並把它們放在一個CSV文件

Question

我試着從過去24小時內收集所有的微博，並把它們放在一個CSV文件

當我這樣做，我得到

_csv.Error: iterable expected, not datetime.datetime 

爲錯誤

誰能幫告訴我如何擺脫這種錯誤，並且可能被以代碼

def get_all_tweets(screen_name): 
# Twitter only allows access to a users most recent 3240 tweets with this method 

# authorize twitter, initialize tweepy 
auth = tweepy.OAuthHandler(consumer_token, consumer_secret) 
auth.set_access_token(access_token, access_secret) 
api = tweepy.API(auth, wait_on_rate_limit=True) 

# initialize a list to hold all the tweepy Tweets 
alltweets = []  

# make initial request for most recent tweets (20 is the maximum allowed count) 
new_tweets = api.home_timeline (screen_name=screen_name, count=20) 

# save most recent tweets 
alltweets.extend(new_tweets) 

# save the id of the oldest tweet less one 
oldest = alltweets[-1].id - 1 

page = 1 
deadend = False 



while len(new_tweets) > 0: 
     print ("getting tweets before %s" % (oldest)) 

     # all subsiquent requests use the max_id param to prevent duplicates 
     new_tweets = api.home_timeline(screen_name=screen_name, count=20, max_id=oldest, page = page) 

     # save most recent tweets 
     alltweets.extend(new_tweets) 

     # update the id of the oldest tweet less one 
     oldest = alltweets[-1].id - 1 

     print ("...%s tweets downloaded so far" % (len(alltweets))) 

     for tweet in alltweets: 

      if (datetime.datetime.now() - tweet.created_at).days < 1: 

       # transform the tweepy tweets into a 2D array that will populate the csv  
       outtweets = [tweet.id_str, tweet.created_at, tweet.text.encode("utf-8")] 

      else: 
       deadend = True 
       return 
     if not deadend: 
      page += 1 
      time.sleep(10) 

# write the csv  
with open('%s_tweetsBQ.csv' % screen_name, 'w') as f: 
    writer = csv.writer(f) 
    writer.writerow(["id", "created_at", "text"]) 
    writer.writerows(outtweets) 
pass 

print ("CSV written") 

if __name__ == '__main__': 
# pass in the username of the account you want to download 
get_all_tweets("BQ")

for row in outtweets: 
      date_str,time_str, entries_str = row.split() 
      #print(a_date,a_time, entries) 
      a_time = datetime.strptime(time_str, "%H:%M:%S") 
      for e in entries_str.split(','): 
       # write the csv  
       with open('%s_tweetsBQ.csv' % screen_name, 'w') as f: 
        writer = csv.writer(f) 
        writer.writerow(["id", "created_at", "text"]) 
        writer.writerows(outtweets) 
       pass 

Answer 1

outtweets永遠只包含數據的單列。 writer.writerows()預計行的列表，也就是一個列表的列表：

[ 
    [columns, in, row, 1], 
    [columns, in, row, 2], 
] 

要設置outtweets這樣的：

outtweets = [tweet.id_str, tweet.created_at, tweet.text.encode("utf-8")] 

這只是一個單行。要將其傳遞給writerows，需要將每行數據累積到列表中，然後將該列表傳遞給writerows。
